Abstract

A NUCLEAR FUEL ROD SUPPORT GRID INCLUDING A PLURALITY OF INTERFOLIATED STRIPS ARRANGED TO FORM A MATRIX OF HOLLOW CELLS TO RECEIVE, EACH ONE, A NUCLEAR FUEL ROD SIDED AND EACH ONE OF WHICH HAS SIDED NUTS. OPPOSITE FORM SHARED WITH ADJACENT CELLS, FORMING EACH OF THE WALLS OF EACH CELL ON ONE SIDE OF THIS ONE PART OF THE PERIMETER OF SUCH CELL AND FORMED ON ITS OPPOSITE SIDE OF THE PERIMETER OF A VARIOUS CELLS AROUND AND AROUND CHARACTERIZING THE GRID BY (A) A FIRST SERIES (50) OF FORMED LITS ADJACENT TO A SUPERIOR END (52) OF EACH WALL (44) OF THE PAIRS THAT DEFINE EACH CELL (42), AND (B) A SECOND SERIES (54) OF HOYUELOS FORMED ADJACENT TO A LOWER END (56) OF EACH WALL (44) OF THE PAIRS DEFINING EACH CELL (42), EACH ONE OF THE FIRST AND SECOND SERIES (50, 54) OF HOYUELOS CONSISTS OF A PAR D E UPPER AND LOWER HOYUELOS (58, 60) THAT PROJECT OUTWARD FROM THE SAME FACE (46) THE WALL (44) IN WHICH THE LIVING HOYUELOS (58, 60, 62) ARE FORMED, AND A CENTRAL HOYUELO (62) WHICH IS SITUATED BETWEEN THE ABOVE AND LOWER (58, 60) AND IS ABOVE THE OPPOSITE FACE (48) OF THE WALL (44) IN WHICH THE HOYUELOS ARE FORMED (58, 60, 62), WHICH ARE SUCH SITES (58, 60, 62) OF THE FIRST AND SECOND SERIES (50, 54) ADAPTED TO BE COUPLED ELASTICALLY AND BY FRICTION WITH FUEL RODS WHEN THEY ARE RECEIVED THROUGH ADJACENT HOYUELOS OF SUCH CELLS.
